Tinijet — Affordable Waterjet Cutting At Home
While laser cutting remains the dominant force for rapid prototyping anything made of plastic, MDF or wood, the real holy grail is the ability to cut metal — something most laser cutters are just not capable of.
In the industry, this is done using extremely high-powered laser cutters, plasma cutters, or water jet cutters. All of which are very pricey equipment for a hacker. Until now anyway. Introducing the Tinijet, the missing tool for affordable water jet cutting.
We first covered this project a few years ago when it was just a university research project called Hydro — it’s since …read more
The USB Type-C Cable That Will Break Your Computer
USB has been on our desktops and laptops since about 1997 or so, and since then it has been the mainstay of computer peripherals. No other connector is as useful for connecting mice, keyboards, webcams, microcontroller development boards, and everything else; it’s even the standard power connector for phones. The latest advance to come out of the USB Implementers Forum is the USB Type-C connector, a device with gigabits of bandwidth and can handle enough current to power a laptop. It’s the future, even if Apple’s one-port wonder isn’t.
The cable of the future is, by default, new. This means …read more
A Better Way to Plug a CPLD into a Breadboard
If you read my first post about a simple CPLD do-it-yourself project you may remember that I seriously wiffed when I made the footprint 1” wide, which was a bit too wide for common solderless breadboards. Since then I started over, having fixed the width problem, and ended up with a module that looks decidedly… cuter.
To back up a little bit, a Complex Programmable Logic Device (CPLD) is a cool piece of hardware to have in your repertoire and it can be used to learn logic or a high level design language or replace obsolete functions or chips. But …read more
This File Will Self-Destruct in 24 hours
[menkveldj] built a service that encrypts files which self destruct in 24 hours. The download link can only be used once. If the wrong people were to get the link and download the file, they’d need many years on a pretty powerful computer to crack the 256AES encryption.
The sender shares a file that is encrypted client side using a password generated Pbkdf2 key to encrypt the data before uploading it to the s3 storage service. The sender is then provided the one-time-use link to share with the recipient. After the first download, or 24 hours, the link and the …read more
Hard Drive Disassembly is Easy and Rewarding
Have any dead hard drives kicking around? Hackaday alum [Jeremy Cook] shows how easy it is to disassemble a hard drive to scavenge its goodies. The hardest part is having the patience and the tools to get past all those screws that stand between you and the treasure inside.
The case screws are frequently of the Torx variety. Any self-respecting hacker probably has one or two of these already, but if you’re in the market, [Jeremy] recommends a nice set that looks way better than ours. Once the case is open, you can find rare earth magnets, bearings, and one …read more
